IPC: G02B6/12
Filed: 1992-02-12
Abstract: PURPOSE:To obtain a has high sensitive and quickly responsive photodetector which effectively converts generated carriers into a photocurrent by laterally forming a PIN type photodiode as a photodetector part on a substrate, and forming an optical waveguide in which a depletion layer generated between two impurity diffused regions becomes a substrate radiation mode. CONSTITUTION:A buffer layer 51 of an optical waveguide 50 of a part interposed to be held between a first conductivity type impurity diffused region 20 and a second conductivity type impurity diffused region 30 provided in the vicinity of a surface of a first conductivity type high resistance semiconductor substrate 10 is thinned, a guided layer 52 of the optical waveguide 50 is approached to the substrate 10, and a substrate radiation mode region R is provided. A light guided through a region G of a guided mode of the optical waveguide 50 is radiated from the region R in which the layer 52 is disposed near the substrate 10 to the substrate side, and absorbed by a part of a depletion layer formed in the substrate to generate carriers. The generated carriers arrive at the regions 20 and 30 to become a photocurrent output.

Title: Real-time monitor device
Inventor: KURIYAMA KAZUYA
IPC: G06F11/30
Filed: 1987-02-05
Abstract: PURPOSE:To execute a software system in real time by setting the conditions for collection and storage of data and at the same time analyzing and editing the system execution based on the collected data to report the analyzing/editing results. CONSTITUTION:When a command is supplied for designation of an analyzing item, an analyzer controller 7 produces the deciding conditions for measurement of the analyzing item from the next input analyzing item and transmits said deciding conditions to a bus analyzer 6. The analyzer 6 produces a deciding condition table based on the received deciding conditions. Then the controller 7 gives a request to the analyzer 6 for transmission of display information with input of a display command for result of analysis. The analyzer 6 extracts the information out of a target system bus by the received request for transmission and produces an information block to send this block to the controller 7. The controller 7 analyzes and edits the received information block to display it. Thus a software system can be measured in real time.

Title: Deccelerating valve
Inventor: TAMAKI SHIGEO
IPC: F02M23/08
Filed: 1979-03-07
Abstract: PURPOSE: To obtain accurate operation at the comparatively slow decceleration by incorporatedly forming the shaft and the contacting part of the diaphragm of the deccelerating valve and leaving a gap between the shaft and the valve.  
     CONSTITUTION: When the throttle valve 3 is suddenly closed, the deccelerating valve pulls out and opens the valve 10 resisting the spring 11 as the strong negative pressure acts upon the air outlet 8 to conduct air from the air passage 7 to the downstream of the throttle valve 3 to reduce the suction negative pressure. At this time, the shaft 15 is moved rightward by the diaphragm 21 shifted by decompression in the negative pressure chamber 16 at the begining of decceleration to encourage the said valve 10 open. At the deccelerating valve of such constitution, the shaft 15 is fixed at the center part of the diaphragm 21, and a gap (d) is left between the top of the shaft 15 and the valve 10. By doing so, the operation at the negative pressure fluctuation can be prevented, and the accurate motion can be obtained at slow decceleration.

Title: Resin composition for extruded sheet
Inventor: YAGI TAKUJI
IPC: C08L67/02
Filed: 1988-02-05
Abstract: PURPOSE:To obtain the title resin composition improved in low-temperature impact resistance, by mixing a thermoplastic polyester mainly consisting of repeating 1,4-cyclohexanedimethylene terephthalate units with a maleic anhydride-graft modified polyolefin in a specified mixing ratio. CONSTITUTION:100pts.wt. thermoplastic polyester (A) having at least 85mol.% repeating 1,4-cyclohexanedimethylene terephthalate units is mixed with 0.5-10 pts.wt. maleic anhydride-graft modified polyolefin (e.g., maleic anhydride-graft modified low-density polyethylene) to produce a composition for extruded sheets. In this way, the low-temperature impact strength of component A can be improved because the maleic anhydride molecules in component B and the 1,4- cyclohexanedimethylene terephthalate molecules in component A undergo a partial crosslinking reaction during melt kneading and therefore component B can be homogeneously mixed with component A.

Filed: 1988-02-05
Abstract: PURPOSE:To calculate a space position with high accuracy by making feature points of a couple of images obtained at sufficiently distant relative positions to correspond to each other and thus obtaining couples of feature points. CONSTITUTION:An image alpha1 at a 1st relative position is stored in a 1st image memory. Further, 2nd-4th images alpha2-alpha4 are stored in 2nd-4th image memories thereafter at specific timing. Then, a distance Vtaus between relative positions is long enough not to make the appearance order of feature points dissident, and Vtaul is such a distance that space coordinates can be calculated with desired accuracy. The (x) coordinate values of feature points of the alpha1-alpha4 are stored in the respective image memories and a feature point couple classifying means couples the feature points corresponding to the appearance order of the feature points and decides whether or not the difference is larger than a specific value. The coordinate values of feature points corresponding to corners A and B on this side are stored and those of feature points corresponding to C and D are not stored. Then a position arithmetic means calculates the space coordinates of the point A and the space coordinates of the B are obtained similarly to calculate the space coordinates and attitude (direction) with high accuracy.

Abstract: PURPOSE:To speed up processing by classifying voices of plural persons as well as a single person and setting the analysis sections of cepstrum peaks of respective groups at the time of registration. CONSTITUTION:An analysis section setting section 4 calculates the optimum analysis sections corresponding to the peaks of the cepstrum supplied from a peak detecting section 2 and supplies the same to an analysis section classifying section 5. This setting section also supplies the analysis section data supplied from an analysis section memory 6 or the predetermined analysis section data to the peak detecting section 2 by the instruction of the analysis section classifying section. The analysis section classifying section 5 compares the optimum analysis section data and the analysis section data stored in the analysis section memory 6, classifies and processes the data and controls the data memory to the analysis section memory 6. The analysis sections made with the voices of the plural persons are classified and set by groups or independently at the time of registration and, therefore, the setting by limiting the analysis sections of the peak detection at the time of recognition is possible. The processing of the voice discrimination is speeded up in this way.
